Flavonol glycosides from Epimedium koreanum.Phytochemistry. 1995 Jan; 38(1):263-5.P
A novel flavonol glycoside named caohuoside-B was isolated from the aerial parts of Epimedium koreanum, along with a known flavonol glycoside, epimedokoreanoside-I. Their structures were established by spectroscopic methods. The new compound was elucidated as anhydroicaritin 3-O-beta-D-(4,6-O- diacetyl)glucopyranosyl-(1-->3)-alpha-L-(4"-O-acetylrhamnopyranoside+ ++)-7-O-beta- D-glucopyranoside.
